Specification of Letters Patent.

Patented Jan. 24, 1911.

i To all whom it may concern.'

' Be it known that we, WILLIAM N. Wiurem' and WILLIAM N. WHITELY, Jr., citizens of the United States, residing at Springfield, in the county of Clark and State of Ohio, have invented certain new and useful Improvements in Manure-Spreadcrs; and lwe do declare the following to be a full, clear, and exact description of the invention, such as will enablehothers-skilled in the art to which it appertains to make and use the same, reference being haldto the accompanying drawings, and to the letters and figures of reference marked thereon, which form a part of this specification.

Our invention relates to improvements in manure spreaders.

The obj ect of our invention is to finely pulverize and evenly distribute bar.; yard and stable manures and other kinds of fertilizers. in a swath much wider than the carrying bed. We have found that not only does thc fertilizer go farther and benefit the land to a greater degree when so distributed, but that itis more convenient because it 'is not necessary to drive back and forth as many times as where the swathis narrow, and with a wider swath which reaches out beyond the track of the wheels it is unnecessary to lap back on the previous swath in order to yniake the edge of one swath meet another.

In the drawings: Figure l. is a side View of the devices of our invention in connection with a spreader bed and running gear of the ordinary type.. Fig. 2. is a perspecti've view of the detainer which is located over the secondary cylinder. Fig. 3. is a peispective rear View of our-improvements. Fig. 4. is a plan view of the rear of a spreader showing the devices ofA our invention. Fig. 5. is an enlarged side view of our invention With the fore part of the bed broken '-away to show themanure conveyer belt.v Fig.(6.vis a perspective view of the rake o1 detainer usec. over the main or primary cylinder. Fig. 7. is an enlarged plan View of one form of the 4secondary cylinder. Fig. 8. is a cross section of Fig. 7.011 lines X-X thereof. Fig. 9. is a transverse section of the secondary cylinder on lines lw---fw of Fig. 7 y

The running gear is f the usual type and need not be particularly described.

The manure conveyer shown isI of the slatted link belt type' but may be of any other well known form or construction. Preferably we employ a tight bottom body and a series of slats passing over same and propelled by a link belt on each side, what is comrnonly called a straw carrier kind conveyor. The manure yconveyer may be driven at various speeds so as to distribute f thick or thin swaths or any suitable amount. As such part of the machine 1s not included in our invention we have not shown any device for this purpose but any-Well known type of conveye'r drive may be used.

IThe primary cylinder is of a well known type in general use but may be of any other suitable form or kind. The principal function of the primary cylinder is to discharge the manure from the bed as it is fed'to it by the conveyor and secondarily to reduce or refine the manure or fertilizer as muchas practicable without interfering with its main function.

Thel secondary cylinder 2. is preferabl constructed with a central core 2a and a shaft 2b passes through the core 2 and is fastened securely. thereto by rivets 3. The shaft 3. bears in boxes 4. which are bolted to arms 5. Another kind of box is shown at G. in Fig. 3. This bearing box swings from a pivot 7. of the arm and is adjusted to take up the slack of the driving chain 8. by means of a screw rod. 9. which is pivotally secured`v to the box 6. and passes through an ear 5a of thc arm,5'. at rear of said arm 5. A nut on the rear side of the ear 5 serves to adjust the box 6. back-and forth to obtain the right tautness of chain. When the chain 8. is adjusted by this means the adjustment of the idler l0. may' be dispensed with and same constructed on a stationary spindle if desired in any well known way. If desired to run the secondary cylinder'2. in the Same rotative direction as the primary cylinder l. as shown by the arrows in Fig. 5., a chain 11.- is employed, in which case the chain adjusting-device described is employed. When this is done the manure will be carried over and to the rear of cylinder 2. Should the secondary cylinder 2. be rotated in the opposite direction from primary'cylinder 1. only the idler 10. need be used to adjust the chain 8. and if so the box 6. may bereplaced by the bearinff box 4.-. which slips over the arms 5 and Iis olted ri idly thereto as shown in Fig. 7 When the idler 10 is adjusted to take up chain slack it is loosely mounted on an arm 12. which is pivoted to the side of the bed and a divided pull rod 13. loosely fastens to arm 12. and passes through an ear 14. and is adjustably secured by a nut on each side of the ear 14. The chain 8. lies on top of the driving sprocket 15. to get the reverse direction of movement for secondary cylinder 2 from primary cylinder 1. while the chain 11. encircles the driver 15. to cause the secondary cylinder 2. to rotate in the same direction as primary cylinder 1. ln practice it has been found preferable to 'rotate the two cylinders in opposite directions so as to tear up the manure by the grinding action resultant.

Preferably each series of blades 2C are made in sections of malleable iron and the sections joined together so that their sides are continuous from about midway of the length of the cylinder to each end as shown in perspective in Fig. 3. The blades 2c form screwlike surfaces to the right and left from about midway of the length of the 'cylinder 2. and are riveted or otherwise fastened to the core 2a. preferably as shown in Fig. 7. they have roughened edges consisting of staggered saw teeth by which the manure is reduced or cut up into small particles. ylihe sides of the blades carry the manure out fromthe center and make a wide distribution or spread. These blades 2u may be pitched at various angles from the longitudinalv line of the bed, but we have found in practice that about 22 degrees pitch gives the best results.

When the secondary cylinder is rotated in the same direction as primary cylinder 1. as indicated by the arrows in `Fig. the same is reversed7 end for' end. and the sprocket 1G. used to drive it in connection with drive chain 11. and main drive sprocket 5. which serves equally well in use with either drivechain 8. or 11. This is done because if not reversed the swath would be narrowedinstead of widened.

In Figs. Z and we show a friction drive device which may beV employed to protect. the machinery from injury when the two cylinders are rotated in opposite. directions. It is preferable, and best results in refining the material to be Worked on areobtained by locating the two cylinders so that their adjacent peripheries are close together. Oc` casionally an unbreakable foreign object, such as a stone or chunk of wood, may get into the load and on being discharged might injure the machinery if no protection were provided for. By means of this friction drive such danger is eliminated as the secondary cylinder 2. may stand still whilc'the primary cylinder 1. continues to revolve so that any such piece lodging between the` cylinders would cause no harm and could. be removed by the operator and the deiuces reA sume their normal functions as before. To accomplish this we provide a driving disk 17, having a spindle end passing through the box 4. and snugly surrounding the shaft 2b and keyed thereto by a key 18. which is partly seated in the shaft 2b and disk 1T. to' hold the same together rigidly yet removably. The sprocket 19. has a disk-shaped portion to fit`the taper of disk 1T. and the sprocket 19. is tightly pressed against said disk 17. byy means of a coil spring 20. fitting over the shaft 2*. and adjusted to thel proper tension by a nut 21. By this means the sprocket 19. may keep on rotating and yetthe secondary cylinder 2. stand still.

lVhen the secondary cylinder 2. is rotated in the same direction as primary cylinder 1. it is not so important to provide a safety device as just described because any foreign objects will be carried oli.2 over the secondary cylinder 2. and same can be discharged thro-ugh the secondary detainer 22. onto the ground, without damage to the machinery, i

by reason of its spring action. lNhen the secondary cylinder is so rotated it will grind the manure against the secondary detainer 22. to the second refining action necessary. j

It has been found in practice that the primary cylinder' cannot acceptably sacritice its main function of discharging thev fertilizer :from the bed for`v that of refining the manure. As it cannot adequately do both of these things a secondary cylinder is provided to thoroughly refine the materials -by a second refining process and to distribute and spread it in an even and wide swath. Commonly in manure spreaders now on the market the manure must be loaded evenly and uniformly and littlel if any, height above the top of the sides of the hed. Ordinarily if the manure is heaped up high or loaded irregularly the result is that it is thrown cti? in chunks or bunches and thicker in the middle of the swath than at the edges so that the machine must be driven back over part of the swath (what is called 'lap ping back) to make the edges meet. By means of the secondary cylinder 9. these ditiiculties and objections are overcome and the same amount of manure made to cover a greater area. and the load can be piled up high so that a smaller and narrower bed will carry as much as the very wide beds co1naccomplish these results, and a secondary.

cylinder not of the particular construction maybe used in connection with a rake or detainer over it, so that there are two cylinders, one in the rear of the other, and both coperating with .detainer mechanism. In' order to thoroughly accomplish the foregoing objects and to cause both of said cyl- -inders to operate and perform their respective functions most etliciently, we preferably provide detainer mechanism to control and hold the material to be acted upon so that it is direct-ed and forced on to each cylinder and onto both joint-ly so that every particle of manure is beaten and torn up and deposited evenly and uniformly and none gets awayfrom this action. lVhile any type of detainer or any device coperating with the primary cylinder 1,.whether it be stationary or otherwise may be used yet it will' be understood that `the functions of the primary cylinder are principally of a discharging nature, and the main Work of this integration and distribution reside in the functions of the secondary cylinder 2 and secondary detainer 22. The result yis thatthe land .is effectively treated, and that/ a, minimum amount of manure will be needed to cover a given area.

"0 The secondary detainer 22. is preferably composed of a plurality of teeth of spring steel so spaced that the manure is forced down on the secondary cylinder as it is discharged by the primary cylinder l. and

` cannot shoot over or above the said cylinder 2. or get away from it without being refined and evenly spread. The detainer' 22. may be a board if desired. The secondary cylinder 2.`can also be of small diameter when 4 protected by the detainer. The speed of the secondary cylinder should, and by .the driving mechanism shown does, exceed that of the primary cylinder 1. The head of the secondary detainer 22. is referably tubular and preferably is pivoted3 in a bracket- 23. which also forms the bearing for the primary detainer 24. Preferably the secondary detainer 2.2. is ivoted so that if it is desired to rotate t e secondary cylinder 2. in the same direction as primary cylinder 1. that it can spring back to let any foreign object pass over and away from the secondary cylinder 2. Without damage to the parts, (but when the secondary cylinder 2. rotates in the opposite direction to the primary cylinder 2. the detainer 22. ma be rigid.) This is accomplished as shown 1n Fig. by means of a lug 25. pinned to the head of the secondary detainer 22. and bearing against an ear 23y ofthe bracket 23. which holds said secondary detainer-in normal position against the ull of a spring 2b interposed between sai bracket 23. and a nut on a 5 spring rod 27. which passes through said lngr 25. and has 'its head resting agalnst nure cannot carry itout of a normal position. The same kind of devices regulate the prnnary detalner 24. which coperates wlth v4:primary cylinder 1. for the same purpose except that the tension of the primary detainer 24. preferably should not be as great' as the secondary detainer 22. because if it were great enough to stop the passage of a chunk of refractory manure the main cylinder would choke by reason of interrupting the constant solid tiow while trying to disintegrate the chunk. This process must be left to the secondary cylinder very largely'or else, as practice has shown, a stiff detainer over the primary' cylinder would cause interminable choking.

lhe tension devices of the main detainer 24. are as follo\vs:--28. represents the lng fastened to the head, 29. Vthe spring for same and 30. the spring rod.V The bracket 23. also supports the head of the primary detainer 24. An upright arm 31. secured to the yside of the bed holds the bracket 23. in

place. y

The main drive chains and other 'primary power transmitting and equalizing mechanisms may be of any well known type not necessary to be described here, nor need be described the levers or other regulating devices operated by the driver.
